We carry a large selection of
pushrods, for nearly every big block lifter/rocker arm combination possible,
from stock replacement to chrome moly racing units for adjustable or roller
rockers. Pushrods that are the stock type with a "ball" on both ends will be
made from 5/16" tubing are for use with stock type non adjustable stamped
steel rocker arms. Pushrods that have a "ball" on one end and a "cup" on the
other will be made from 3/8" tubing and are meant for use with adjustable or
roller rocker arms. Length measurements listed for ball/cup type pushrods
are to the TOP of the cup, or the "overall" length of the pushrod. If you
are measuring to the bottom of the ball end of the rocker adjuster, you must
subtract the depth of the cup (about .150") from our "overall length"
measurement.
READ THIS BEFORE ORDERING: Pushrod lengths
listed are for "average" applications. As much as we'd love to
sell you pushrods in one shipment with rocker arms and all the other parts
you may need, nobody will be able to tell you the exact length you will need
from just a phone conversation. Everything from the block and head deck
heights, lifter type/brand, cam base circle size, head gasket, valve stem length, rocker
type, and more will all add up to affect your pushrod length. The only way to be 100% sure
is to do a mock up of your engine and use an adjustable checking pushrod to
verify the length you need BEFORE you order. We sell these adjustable
checking pushrods (you can find them below.) Some applications may require
custom length pushrods. Keep in mind that hydraulic lifters will allow some
play due to the travel of the lifter's plunger, and adjustable rockers will
allow for adjustment as well with the adjustment screw, so lengths don't
have to be accurate to the thousandth of an inch, however it is ideal to
have the adjustment screw with only zero or one thread showing out of the
bottom of the rocker arm. The adjustment screw should NOT be all the way in
or out to compensate for incorrect length pushrods. Please verify the length
will work for your application before ordering. ANY RETURNS OR EXCHANGES WILL BE SUBJECT TO OUR RESTOCKING FEE, (listed on our terms and conditions page.) Measured
lengths on cup type pushrods are to the very TOP edge of the cup, not the
bottom of the cup where the ball adjuster will sit.
Our new AMERICAN MADE cut to fit pushrod sets are exactly what you need if you don't know exactly what your finished pushrod length should be. These 3/8" .060" wall heavy duty pushrods come with the ball end (bottom end) of the pushrods assembeled, however the top (cup) end comes unassembeled, so that you can cut the tubing down to the exact length you need. Maximum length is 9.500" (if they were put together without shortening the length,) and these pushrods can be cut down to any length shorter than that. While we recommend cutting the tubing on a lathe for the straightest possible cut, if you are in a pinch, these can also be cut with a cutoff wheel. The ends can be pressed in with a press, or (in a pinch) tapped in with a mallet if necessary. A great way to ensure you'll be getting the correct length pushrods, without having to mess with multiple orders, custom made parts, etc.

Shown here is our checking pushrod tool. Use this for applications with adjustable rocker arms which use the ball on the bottom end, and the cup on the top end. This is basically a 3/8" pushrod which has been cut and threaded, so that it can be screwed in and out (or adjusted) once it is fit in the engine to determine the correct length pushrod you will need for that application.
